What Niebuhr Gears does

Niebuhr Gears A/S is a privately held Danish precision gear manufacturer founded in 1972 in Ikast, Denmark. The company designs and produces five core gear product lines — cylindrical gears, heavy-duty gears, worm gears and worm wheels, bevel gears, and spiral bevel gears — using a modern machine park of more than 100 CNC machines capable of producing components up to five meters in diameter. Production is split between the Danish headquarters and a wholly owned Chinese subsidiary, Niebuhr Gears Co. Ltd, based in Tianjin, with both facilities holding ISO 9001, ISO 14001, and ISO 45001 certifications and APQP4Wind qualification for the wind sector.

The company's commercial focus is on custom, co-developed gear solutions for blue-chip OEMs. Its primary vertical is wind energy, where it supplies yaw gears up to five meters in diameter to Vestas (a partnership running since 1979) and serves as a preferred supplier to Siemens Gamesa. Additional named customers span marine propulsion (Rolls-Royce Marine, preferred supplier), construction equipment (Engcon as sole supplier of worm gears since 2016; Haarup as a 20+ year supplier for concrete mixer gearboxes), and heavy-duty vehicles (Sisu Axles). Quality assurance encompasses CMM measurements, MPI testing, hardening reports, and First Article Inspection.

Revenue is generated through quote-based B2B sales of custom-manufactured components under multi-year supply contracts, with go-to-market executed by a dedicated sales team led by a Chief Sales Officer and including area sales managers for Germany and Norway. Pricing is not publicly disclosed; multi-language sites (Danish, German, English, Swedish, Chinese) and dedicated regional sales coverage indicate an export-oriented business serving European and Chinese industrial OEMs. The company is family-controlled, with Rasmus Niebuhr serving as CEO, and does not disclose revenue publicly.
